Package: cryptsetup
Version: 2:1.7.0-2
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
I installed debian jessie, during which time the installer warned me that it
would be inadvisable not to use encrypted swap. Who am I to disagree? I later
upgraded to debian stretch/testing but as far as I can tell looking at the diff
between 1.6.6-5 and master at git://anonscm.debian.org/pkg-cryptsetup/cryptsetup
the bug is almost certain in jessie also. Does anyone else even use encrypted
swap?
* What exactly did you do (or not do) that was effective (or
ineffective)?
I edited /lib/cryptsetup/cryptdisks.functions to have the "stop" command check
for the "swap" option in the /etc/crypttab line and ran a new function named
"do_unswap()" to call "swapoff -a; do_close; return 0" to ensure that the
encrypted disk would be properly shut down on restart.
* What was the outcome of this action?
Encrypted swap on this machine is great again.
* What outcome did you expect instead?
This is what I expected since I verified manually before modifying the
cryptdisks.functions file that if I properly turn off swap and close the
encrypted partition before rebooting the swap partition would indeed be active
by the time i log in next.
I'll probably try submitting a patch or something.
